Lenna could not help touching herself as she watched her children fuck. Her handsome young son was expertly thrusting his sister, and for some weird reason, Lenna found herself wishing it was her pussy her son was fucking. She was also really impressed with her son as she watched him move his hips timely, meeting the rythm of Sharon's labia, humping her until she was on the cusp of her orgasm. He was definitely not as inexperienced in sex as she thought he was.
Sharon let out a trembling moan as her brother fucked her in a missionary position, quickening the pace, pleasure rippling through her body, and spread her legs wider. She opened her eyes and let out a whining moan as her gaze continued to look deep into her brother's eyes.
